P. GERHARDT. METAL DOOR AND WINDOW FRAME CONSTRUCTION.

APPLICATION FILED MAY 4, 1912.

' 'described and more Sib. Y i

lhereby declare that the Vfollowing is a full,

clear, and' exact description thereof, reference'beinghad to the accompanying draw ings, and to thevletters of reference marked thereon, tion.V i

Thisinvention relates to .improvements in metal frame construction for doors or .windows and consists 4of the matters hereinafter particularly pointed out in theappended claims.

, My .improved metal` frame lconstruction may be used both for door frames andwindow .frames-and as shown 'herein is illusv trated as applied to door frames.

In theA drawings t-F igure 1 view representing a door-frame .made 1n vaccordance with my invention,

. front elevation.A Fig.'2 is a view represent ing a horizontal section through onejamb member of the door-frame in a plane indicated by the line 2-2 of Fig. l. Fig. 3 is a View representing a vertical section through the head ,member of the door-frame in a` plane indicated by the line 3 3 of Fig. 1'. Fig. 4 is a view representing a transverse section through the bottom ends of the jamb members of the door frame in a plane'indicated by the line 1-4 view representing a section similar to that shown in Fig. 3,

My improved metal frame construction consists of'transverse. and upright members to form the frame and in the case of 'ajdoorframe, as shown in the drawings, comprises connect the lower ends 4of the jambs together and hold them in proper spaced relation, Each framemeinber is made of metal which is rolled so as to Abe substantially U-shaped in cross-section, as clearly illustrated i'n Figs.

2 and 3, the transverse base of the U forming the face of the jamb andthe legs of the U', the sides of thej amb.

part of the Wall 15. Said lwall may be of tile or of any other familiar construction. l

|The face member 13 of the frame member is offset at each side of a longitudinal me dianvline to form' oppositely facing doorstops 16, 16 on its outer surface and a longitudinally ex ,nding channel l? on` its inner surface.

18, -18 indicate longitudinally extending,

laterally spaced flanges or ribs which form' extensions of the sides of t-he channel 17 4and project inwardly beyond the face member 13. At the free margins of the sideA members 14, 14 of the metal frame'member areA provided ribs 19, 19, which are faced in` planes parallel' to the planes of said side members and areslightly offset outwardly from said planes. v V When the frame is in place the jambs rest upon the Hoor members, and where a cement `floor 23 isv used, areembedded-therein and each frame member is located with its face kmember 13 spaced fromv the edge of the wall 14, 14 spaced l5 and with its side members at'each side of said wall. The spaces'be-` tween the marginal part of'sthe wall and the metal frame are then filled with cement,con Vcrete or plaster in the usual manner. In the transverse member or members of the frame andin the case of a door-frame in the headmember alone, there is embedded in the concrete contained ,within the channel 17, a rod or bar 20 which is made longer than the so as to project laterally at each end beyond said frame. The laterally projecting ends 20a, 20? of the rod 20 (indicated by dotted lines in inthe wall so as to hold Ait rigidl right. position. If desired, the ends of the rod 2O may bevturned upwardly (indicatedby broken lines as 20b in Fig. 1) and anchoredin the wall above'the frame.

' yThetie-members 12@ y in an upprojecting are 'riveted to the side members 14 of the j'ambs of the'door- Fig. 1), ,are anchored 12, as shown are frame near the lower ends thereof, and are embedded with saidlower ends in the concrete which4 forms the fioor.

The .obj ect of the offset-ribs 1'9 is to protect the sides of the jamb from.

scratching when the plaster is placed on the Wall adjacent said jambs. Said ribsibeing offset from the planes of the sideamenbers of the metal jamb form a groindr the plasterer andA prevent the tools used in plastering and the plaster itself from coming into contact with the jamb. This is an important feature since the metal frames are finished at the factory before installation and when enameled or provided with other expensive finish, it is expensive, and in some cases impossible, to reinish them after they are in place.

The rib of concrete which projects 'into the channel 17 greatly adds. to the rigidity of the connectionbetween the door-'frame and the marginal part of the wall about the doorway and together with the* extending ends of the bar 2O securely hold the doorframe in upright position.

I prefer to make the members of my metal frame construction in one piece but -in case of wallsof greater vthickness requiring a wider face member, said frame members may be made of more than one piece. Such a construction is illustrated in Fig. 5. In this case 24 indicates the face of the frame member and 25, 25 the sides. 26, 26 indicate the offsets in the said face, 27 vthe channel, and 28, 28 the longitudinally .extending-p flanges or ribs projecting inwardly from said face member. The-channel 27 in this case is made very wide and the frame member is made in three parts, two parts 25, 25, each of which forms one of the sides and a part of theface including an offset 26 and a part of the' channel 27 and a plate 27 whichl forms the intermediate part of the channel face. Said parts are rigidly attached together bybiazing or in any other convenientniaiiner. 'In the case of such-wide channels, two bars 28 are preferably used in the transverse members of the frame. If desired a bar or rod may also be'used in the channel of the vertical jamb members. I claim as my invention z- 1. A -metal frame construction foi' doors or windows comprising frame-members, each substantially U-sliaped in cross-section, each frame member having a face and two sides,v

v and the free margins of the sides of said frame-members being provided with longitudinal ribs having exposed faces outwardly offset from said side to define the associated wall-planes and prevent the tools used in facing said Walls from marringthejsurfaces of said sides.

2. A metalframe construction for doorsv or windows comprising frame members, each substantially U-shaped in cross-section, each frame `member comprising a face and two sides and the face being offset intermediate said two4 sides to form a longitudinally extending channel, said frame member being provided with laterallyspaeed, longitudinal ribs orv flanges forming` inwardly projecting.

extensions of the sides of said channel and the free margins of the sides of said frame membersbeing provided with= longitudinal -ribs having exposed faces outwardly offset from said sides tofdefine the associated wall planes and to prevent the toolsused in facing` said walls from marring the surfaces of said sides. D

3. A metall frame construction for 'doors or windows comprising frame members, each v substantially U-shaped in cross-section, each frame membercomprising `a face and two sides and the face being offset intermediate said sides to form a longitudinally extending channel, said frame member being provided with laterally spaced, longitudinal ribs or ianges forming inwardly projecting extensions of the sides of lslid channel, in combinatin with a rod or bar adapted to'be embedded within saidchannel and having ends projecting beyond said frame for anchoring` in the walls about said door or window.
